The control valve for a tributary channel in an irrigation area provided by the utility model can select the control angle of the fixed angle to normally open the valve or control the normally closed valve as needed, and can also control the maximum flow rate as needed and automatically adapt to the flow rate of the water in the main channel. It is simple to operate, has better adaptability, and is more convenient for users to control and use. However, during the application of this technical solution, the water-facing surface of the valve is affected by water pressure, which is time-consuming and labor-intensive to open. If the driving mechanism is damaged, manual operation will be more inconvenient. There are also technical problems such as the inability to divert the water flow in the channel and to use the force of the water flow to make opening the gate more time-saving and labor-saving.

[0008] As a preferred technical solution of the utility model, the mounting ear plates are symmetrically arranged on both sides and the bottom of the two ends of the frame, and the top end of the lifting screw passes through the top end of the frame and the inside of the manual-automatic opening and closing machine.

[0009] As a preferred technical solution of the utility model, the resistance reduction component includes a pad protection slide plate, which is arranged on both sides of the gate plate, and graphite coatings are arranged on both ends of the inner side of the lifting guide groove.

[0010] As a preferred technical solution of the utility model, the pad protection slide plate is symmetrically arranged at both ends of the gate plate, and the graphite coating is evenly distributed at both ends of the inner side of the lifting guide groove.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. By arranging a flow guide assembly at the bottom of the front end of the gate, the water flow on the water-facing surface of the gate can be more easily diverted away through the flow guide cover with an arc-shaped cross section when the gate is opened, thereby reducing the resistance of the water flow to the opening of the gate, and the water flow can generate an upward thrust when passing under the flow guide cover, so that it is more labor-saving to open the valve and reduce the energy consumed by opening the valve. In addition, the structural strength of the connection between the flow guide cover and the gate is improved by the fixing plate to avoid damage to the flow guide cover caused by water flow impact;

[0021] As a further implementation of this embodiment, Figure 1 , Figure 2 and Figure 3As shown, a deflector 5 is provided at the bottom of the front end of the gate plate 4, and the deflector 5 has an arc-shaped vertical section. The deflector 5 with an arc-shaped section is more likely to guide the water flow on the water-facing surface of the gate plate 4 away. A fixing plate 9 is provided between the inner side of the deflector 5 and the front end of the gate plate 4, and the fixing plates 9 are arranged at equal intervals between the inner side of the deflector 5 and the front end of the gate plate 4. The fixing plates 9 improve the structural strength of the connection between the deflector 5 and the gate plate 4, and avoid damage to the deflector 5 caused by water flow impact, thereby effectively reducing the resistance of the water flow to the opening of the gate plate 4, and the water flow can generate an upward thrust when passing under the deflector 5, so that it is more labor-saving to open the valve and reduce the energy consumed by opening the valve;

[0022] When the gate is opened, the water flow on the water-facing surface of the gate plate 4 can be more easily diverted by the deflector 5 with an arc-shaped cross section, so as to reduce the resistance of the water flow to the opening of the gate plate 4, and the water flow can generate an upward thrust when passing under the deflector 5, making it easier to open the valve, and the connection strength between the deflector 5 and the gate plate 4 is higher through the fixing plate 9;

[0023] As a further implementation of this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, a resistance reduction component is arranged between the two sides of both ends of the gate plate 4 and the inner side of the lifting guide groove 7, and the resistance reduction component includes a pad protection slide plate 6, which is arranged on both sides of both ends of the gate plate 4, and the pad protection slide plate 6 is symmetrically arranged at both ends of the gate plate 4, and the pad protection slide plate 6 is used to reduce the friction between the gate plate 4 and the inner side of the lifting guide groove 7 when opening and closing the valve, thereby reducing the wear of the gate plate 4, and the two ends of the inner side of the lifting guide groove 7 are provided with a graphite coating 10, and the graphite coating 10 is evenly distributed at the two ends of the inner side of the lifting guide groove 7, and the wear resistance of the contact surface is improved by the graphite coating 10, so that the gate plate 4 can be lifted and opened and closed more smoothly, and the feasibility is strong;

[0024] Specific working principle:

[0025] When using the channel control valve, the manual and automatic opening and closing machine 8 can use the worm gear to drive the lifting screw 3 to rise and fall in an electric or manual manner, thereby driving the gate plate 4 to rise and fall on the inner side of the lifting guide groove 7. At the same time, the protective slide plate 6 is used to reduce the friction between the gate plate 4 and the inner side of the lifting guide groove 7 when opening and closing the valve, so as to reduce the wear of the gate plate 4. The graphite coating 10 arranged on the inner side of the lifting guide groove 7 improves the wear resistance of the contact surface, so that the gate plate 4 can be lifted and opened and closed more smoothly. When opening the gate, the water flow on the water-facing surface of the gate plate 4 can be more easily diverted through the deflector 5 with an arc-shaped cross section, so as to reduce the resistance of the water flow to the opening of the gate plate 4. When the water flow passes under the deflector 5, an upward thrust can be generated, making it easier to open the valve, thereby opening and closing the valve more efficiently and stably to control the opening and closing of the channel.
